The DASS-10 was developed by Prof Kim Halford in consultation with Dr Aaron Frost in response to the lack of robust progress monitoring tool that is brief, reliable, valid, and freely available in the public domain.
The items were taken from the original Depression Anxiety and Stress Scales developed by Lovibond and Lovibond. Permission was sought and granted by Lovibond for this purpose on the proviso that it is clearly not associated with the original measure.
It has been in use by Benchmark Psychology in Brisbane since 2013 and has guided the treatment of over 3000 clients by more than 30 clinicians.
